SAFETY-RAZOR.

Specification of Letters Patent.

Patented Nov. 9, 1920.

Application filed February 2, 1920. Serial No. 355,757.

To all whom it may concern Be it known that I, linnny-Sorrnnsmonn, a citizen of the United States, residing at the borough of h lanhattan, city, county, and State of New York, have invented certain new and useful Improvementsin Safety- Razors, of which the following is a specification, reference being had therein to the accompanying drawings, which form a part thereof.

My invention relates to safety razors, and more particularly to a razor of this type which is so constructed as to be capable of being made of sheet metal throughout, excepting as to the removable blade.

While a safety razor made in accordance with my invention may be made at a remarkably low cost because of its sheet metal construction, the very simplicity in its structure necessitates care in. the formation of the coacting parts so. as to insure accuracy in the positioning ofthe blade with rela tion to the guard and avoid the presence of sharp edges which may contact with the skin of the user, the edge/thereof ad acent the sharpened edge of the blade being so bent upon itself as to present a short curve of sufficient thickness to act as an effective The entire structure comprises but four parts, a guard plate having a handle soldered or otherwise firmly and permanently secured thereto,-a razorblade and a retaining or slide plate removably mounted upon said guard plate, there be1ng no screws, bolts, rivets or other fittings neces- V sary in the assembling of the device.

The invention consists primarily in a safety razor comprising a sheet metal guard plate having one longitudinal edge thereof turned upon itself to form a guard for the edge of the razor blade, and havlng the opposite side edges thereof turned in the opposite direction to form guide keepers extending at right angles to said guard at opposite edges of said guard plate, said guard plate having rectilmeally arranged, upwardly extending projections between said gulole keepers, and'a retaining plate slidably mounted in said guide keepers and adapted to engage said projections, whereby said retaining plate adjacent the cutting edge of the blade, will beforced into engagement' therewith to bind said blade upon said plate; and in such other novel features of construction and combination of parts as are hereinafter set forth and described, and more particularly pointed out in the claims hereto appended.

Referring to the drawings,

Figure l is a perspective view of a safety razor embodying my invention with the re taining plate removed from the guard plate, but in position to be applied thereto Fig. 2 is a bottom plan view of the assembled structure; an i F ig; 3 is a side view thereof upon a larger scale with the guard plate, razor blade, retaining plate, and the upper portion of the handle, shown in section. 1';

Like letters refer to like parts throughout the several views.

In the embodiment. of my inventionshown in the drawings, a indicates a. guard plate, the forward edge of which has its sides mitered to form a flap which is bent downwardly and rearwardly upon the body of said plateto reinforce this edge of said plate a and at the same time form a short curved surface which will serve as a guard 64 adjacent the cutting edge ofthe blade I). In forming the inturned flap a I makeit slightly shorter in width than the said plate a so as to leave shortgage tongues a which may be flared upwardly slightly so as to prevent displacement of the blade in .relation to the said guard portion a when mounting the retaining plate in relation to said blade. 3 r i The side edges of saidplate a are turned upwardly and inwardlyto form the guide keepers 0 at opposite sides of the plate a, extending at right angles tolthe guard a of said plate; These guide keepers afford sufficient clearance to receive theblade b and also to receive the retainingplate d .WhlChis adapted to be slidably mounted upon said plate a between the blade 6 and the keepers c in a manner to force said blade 6. firmly'ilo against the plate a and hold it against posthe'under face of said plate (Z while it is be-.

ing forcedbetween the blade and'th'e said keepers c', and at the sametime serve back gage for accurately positioning the blade in relation tothe guard as. v

To facilitate the insertion" and removal of the plate (Z, .l for-in a downwardlycurved handehold thereon at d" and. foldthe edge thereot upon-itself as shown at d to avoid V the presence ol any edges having linsthereon which might scratch the fingers oi the user, Furthermore the hold'd will limit the movement of the plate 62 toward: the, guard portion oiltheplate a by, engaging with i back edge oisaid'plate, which latter is folded upon itsellas'shown ata" to reinforce the back: edge ofitlie plate and. at the-.sanietiine avoid the presence of any sharp at this point.

When the blade is thus positioned upon the plate a, the retaining plate disinserted beneath the keepers ,c and jorced j downwardly slightly" to bring the rorward edge thereof above. the projections 6L6. Said-plated is then forced toward the guart a until thehand-"hold cl thereon engages-the V rear edge of the plate 'llhe tongues a will prevent any displacement ofthe blade during this movement either-staining plate.

Hence considerable accuracy is required in'the formation o flt'he projecti e -e and the lugs a 'to insure the desired parallelism in the guard a and" the cutting edgeof thebladehparticularly as no means for adjustment oi the blade is afforded The ton ue'sa 'mi ht be dis aensed with andzthe} thumb bi -the user'relied-upon to secure the desired accurate positioning of the blade with relation to the guard, but particularly with a'cheap razor, it is advisable to provideeve'ry safeguard to insure accuracy in the positioning of the blade and prevent the fingers of the user being cut in mounting the blade upon the guard plate.
